Abstract: A controller is presented having one or more interfaces through which to communicate with a plurality of memory dies with multi-level memory cells and an interface through which to communicate with a host. The controller also contains a processor that is configured to receive a command from the host to program data in a plurality of lower pages and a plurality of upper pages of the multi-level memory cells. The controller detects an indication from the host that indicates which previously-programmed lower pages from a previous program command are at risk of being corrupted by the programming of the upper pages from the received program command. Prior to programming the upper pages, the controller backs up the previously-programmed lower pages from the previous program command that are at risk of being corrupted but not the lower pages of data programmed by the received program command.

Abstract: A method and system writes data to a memory device including writing data to varying types of physical write blocks. The method includes receiving a request to write data for a logical block address within an LBA range to the memory device. Depending on whether the quantity of valid data in the memory device meets a predetermined criteria, the data is written to a specific chaotic block, a general chaotic block, or a mapped block. The mapped block is assigned for writing data for the LBA range, the specific chaotic block is assigned for writing data for contiguous LBA ranges including the LBA range, and the general chaotic block is assigned for writing data for any LBA range. Lower fragmentation and write amplification ratios may result by using this method and system.

Abstract translation: 一种方法和系统将数据写入存储器件，包括将数据写入不同类型的物理写入块。 该方法包括接收向LBA范围内的逻辑块地址写入数据到存储器件的请求。 根据存储装置中的有效数据的数量是否满足预定标准，数据被写入特定混沌块，一般混沌块或映射块。 分配映射的块用于写入LBA范围的数据，特定的混沌块被分配用于为包括LBA范围的连续LBA范围写入数据，并且分配一般混沌块用于为任何LBA范围写入数据。 通过使用该方法和系统可能导致较低的分段和写入放大率。

Abstract: A method and system for relocating selected groups of data in a storage device having a non-volatile memory consisting partitions with different types of non-volatile memory. The method may include determining whether data received a first partition meets one or more heightened read probability criteria and/or heightened delete probability criteria. If the criteria are not met, the received data is moved to a second partition, where the first partition has a higher endurance than the second partition. The system may include a first non-volatile memory partition and a second non-volatile memory partition having a lower endurance than the first, where a controller in communication with the first and second partitions determines if a heightened read probability and/or a heightened delete probability are present in received data.

Abstract: A controller communicates with a plurality of multi-chip memory packages. Each multi-chip memory package comprises a plurality of memory dies, each having a respective plurality of memory blocks, some of which are good and some of which are bad. The controller determines a number of good blocks in each memory die. Based on the determined number of good blocks in each memory die, the controller selects a memory die from each of the multi-chip memory packages to access in parallel, wherein the selected memory dies are not necessarily all in the same relative position in each multi-chip package. The controller then creates a metablock from a set of good blocks from each of the selected memory dies, wherein a maximum number of metablocks that can be created across the selected memory dies is determined by a lowest number of good blocks in the selected memory dies.

Abstract: Host system data files are written directly to a large erase block flash memory system with a unique identification of each file and offsets of data within the file but without the use of any intermediate logical addresses or a virtual address space for the memory. Directory information of where the files are stored in the memory is maintained within the memory system by its controller, rather than by the host. The file based interface between the host and memory systems allows the memory system controller to utilize the data storage blocks within the memory with increased efficiency.
